As per my under standing u need to restart named daemon at primary. kill -1 would be fine. not 100 % sure so do it with care

You need to increment the serial numbers in any database file you modified. Then run sig_named restart on the primary and then run sig_named restart on the secondary

Ok here goes.

If you are adding a new zone (say a new domain you are now resolving) modify named.conf and add the zone entry.

Then in the zone directory add the zone file.


If you are just adding hosts to an existing zone edit the zone file. Add the host, and make sure to update the serial number at the top of the zone file. This is what is used to tell slaves that the zone has changed.

Then do:

ps -ef | grep named
find the process id and issue

kill -1 pid-of-named

This will recycle named and cause it to load the new zone file. The slave servers will also realize that an updated zone is out there and should initiate a zone transfer of the updated zone.

Just an FYI. There is no need to restart the seconday server when you update the primary correctly.
